times as big, as the Diameter of the Moon appears to the nal^d 
Eye. I faw the Limb pretty round,and very well defin'd with- 
out radiation. The parts of the Phafis of it had various degrees 
of Light. About a and/, the North and South poles ofit^ ( in 
thcFi£,§^) 'twas fomewhat darkcrj and by degrees it grew 
bl ighter towards b» and e, two Belts or Zones ; the one of 
which(6) was afmalldark Belt croffing the Body Southward ; 
A djoyning to which was a fmal Line of a fome what lighter part; 
and below that again, Southwards, was the great black 5^/^ 
Between thatj and the other fmaller black Belt, was a pretty 
large and bright ^ne s but the middle was fomewhat darker 
than theedges.I perceiv'd,about 3^- ly'^'near the middle of this, 
^iVtTjdarkjoundspoty like that reprefented at^, which was not 
to beperceiv'd about half an hour before : And I obfcryed it^ 
in about 10. minutes time to be gotten almoft to ^ keeping 
equal diftance from the SateUes h, which moved alfb Weft- 
wardly, and was joynd to the Disk at at^^^'- fij'"- After 
" which^ the Air growing very hazy, and(' as appeared by the 
Barofcope^ very light alio ( in weight^ I could not obferve it ; 
So that it was fujfficiently evident, that this black Spot was no- 
thing elfe, fave the (hadow of the Satelles hy Eclipfing a part of 
the Face of Jupiter, About two hours before, Ihadobferved 
a large darker fpot in the bigger B^/^ about \, which in about 
an hour ©r little more ( for I did not exadly obferve the time, 
nor draw the Figure of it) moving Weftwards, difappear'd. 
About a week before^ I difcover d alfo^ together with a Spot 
in the Belt c. another Spot in the Belt e, which kept the fame 
way and velocity with that of the Beltc. The^ther three Sa- 
tellites in the time of this Eclipfe^made by the Satelles, were 
Weftwards of the Body o( Jupiter > appearing as bright through 
the Tube, as the ^ody of ^w/^/V^r did to the naked Eye, andl 
was able to fee them longer through the Tube, after the day- 
light came on ,^ than I was able to fee the ^ody of Jupiter with 
my naked eye, 
A late Obfervation ahout?>^t\xm made by the fame.
